Anyone else ever seen this effect on an LCD display, or have any thoughts
on
how it could occur ?

Might the screen have been an LCD, or a CRT, which "bounces" the image
onto a translucent display screen via a mirror or lens arrangement of
some sort? All sort of opportunity for linearity and misalignment
issues with that sort of arrangement.

No evidence of any kind of 'line structure' on the display Dave, so I don't
think that it was any kind of CRT display, direct or indirect. It was just a
typical flat panel display on a bulkhead wall, the other side of which was a
toilet. As well as these main bulkhead displays (there were several
throughout the length of the aircraft) there were also 'repeater' displays
suspended from the cabin ceiling at regular intervals over the left and
right aisles. These were definitely small LCDs and were perfectly linear in
both axes, which rules out there being any intrinsic non linearity in the
original picture before it was placed on whatever media was used onboard the
aircraft. It's a strange one, for sure ...
